A RESTful instance of OpenWFEru (ruote) powered by Sinatra (http://sinatrarb.com)


== getting it

To get Ruote and Ruote-Rest :

    git clone git://github.com/jmettraux/ruote-rest.git

Then

    cd ruote-rest 
    rake install_workflow_engine

( or get a prepackaged release of ruote + ruote-rest at http://rubyforge.org/frs/?group_id=2609 )

To prepare the development database

    rake recreate_mysql_db

Expects a mysql db with a 'root' admin account with sufficient access rights. 
It will create a database named "ruoterest_development".

(
To prepare the test database

    rake recreate_mysql_db stage=test

To prepare the dev database with the admin 'toto'

    rake recreate_mysql_db dbadmin=toto
)


== starting it

    bin/start


Then head to

    http://localhost:4567/processes


== interface

By default, XML representations will be returned. The 'Accept' header is used 
to determine which representation the client expects. 

The 'format' query parameter can be used to override that, like in

     GET /processes?format=json

For debugging purposes, you can force to a text/plain content type 
with 'plain' :

    GET /workitems?format=json&plain=true


=== /processes

GET /processes

    lists all the [business] processes currently running in the engine


POST /processes

    launches a new process instance


GET /processes/{wfid}

    returns the detailed status of a given process instance


GET /processes/{wfid}/representation

    returns the JSON representation of the current process instance tree


DELETE /processes/{wfid}

    cancels a business process instance


=== /expressions

GET /expressions/{wfid}

    returns all the expressions of a business process instance


GET /expressions/{wfid}/{expid}

    returns one expression


GET /expressions/{wfid}/{expid}?format=yaml

    (note that using the Accept header is the best way to do that)


PUT /expressions/{wfid}/{expid}

    updates an expression, live. Expects a YAML version of the expression


DELETE /expressions/{wfid}/{expid}

    cancels one expression


=== /workitems

GET /workitems
